LADDER.

Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed. February 18, 1904:. Serial No. 194,156.

Be it known that I, HENRY W. PEAsE, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Ladders, of which the following is a specification.

The principal object of the present invention is to provide a simple,efficient, and com paratively inexpensive device which may be detachablyapplied to any ladder and which will prevent its base from accidentallyslipping.

To these and other ends hereinafter set forth the invention comprisesthe improvements to be presently described and finally claimed.

The nature, characteristic features, and scope of my invention will bemore fully understood from the following description, taken inconnection with the accompanying drawings,forming part hereof, andinwhich- Figure 1 is-an elevational view illustrating the detachablefoot in application to a ladder. Fig. 2 is a front view, drawn to anenlarged scale, of the lower portion of the ladder shown in Fig. 1. Fig.3 is a view in section, illustrating a modification of the detachablefoot; and Fig. 4 is a side view illustrating another modification.

In the drawings, 1 and 2 represent th sides of a ladder, and 3 therounds thereof.

4 is a foot detachably connected with the ladder, and it consists ofside pieces 5 and 6 and cross pieces 7 and of adjustable tiepieces orlinks which connect its base with the base of the ladder. The foot isdetachably connected with one of the rounds 3 by providing its sidepieces with notches for the reception thereof. As shown in Fig. 1 thenotches are out in the ends of the side pieces 5 and 6, and as shown inFig. 3 they are of the form of hooks having lateral openings, and thesehooks may be formed in or connected with the side pieces. The tie-piecesmay be variously arranged and made adjustable. As shown in Fig. 1 thetie-piece 8 consists of a straight notched bar, the notches beingarranged to engage a stud9 on the side of the ladder. As shown in Fig. 3the tiepiece 9 is provided with a series of holes, any one of which maybe engaged by the bolt 10. As shown in Fig. 4 the tie-piece 11 is curvedand slotted for the accommodation of the set-screw 12, carried by theside of the ladder.

Many other modifications of the tie will suggest themselves to thoseskilled in the art.

The ends of the sides 5 and 6 may be beveled, as shown'at 13 and 14, inopposite directions to secure a good bearing-surface. If desired, thetie-bars shown in Fig. 1 may be hooked onto the lowest' round 3 of theladder, in which case the part 9 could be dispensed with. The describedfoot attachment may be obviously applied to ladders of almost anycommercial width, as it is not essential that the attachment should beas wide as the ladder, and, in fact, it may be considerably narrower.Moreover, the attachment is simple in construction and comparativelycheap, while at the same time efiicient in preventing accidentalslipping of ladders, and compact and capable of easy transportation andrapid application and detachment.

It will be obvious to those skilled in the art to which my inventionappertains that modifications may be made in detail without departingfrom the spirit thereof. Hence I do not limit myself to the preciseconstruction and arrangement of parts hereinabove set forth, andillustrated in the accompanying drawings; but,

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is.-

1. An attachment for ladders comprising a foot adapted to rest at itslower end on the ground and provided at its upper end with hooks havingnotches for detachably engaging a ladder-round and at the lower end witha tie-piece for detachably engaging the ladder near its base,substantially as described.

2. An attachment for ladders comprising a foot adapted to rest at itslower end on the ground and provided at its upper end with notches fordetachably engaging a ladderround and at the lower end with means foradjustably connecting it with a ladder-base, substantially as described.

In testimony whereof I have hereunto signed my name.

HENRY W. PEASE.
